7 Application filed July 22, 1921. Serial No. $86,732.

To all whom it may concern:

Be it known that I, ALFRED J. AsELIN, a citizen of the United States, residing at Ba City, in the county of Bay and State of ffiichigan, have invented certain new and useful Improvements in Marking Hammers, of which the following is a specification.

This invention relates to improvements in marking devices and more particularly to a novel and improved marking hammer, whereby an impression may be made in an object or article of manufacture when the plate is struck by the force of the hammer.

. The primary object of the invention resides in the construction of an improved marking hammer wherein a plurality of adjustable marking or numbering discs are disposed in the head thereof in such manner that when the hammer strikes an object such as a railroad tie, piling, bridge timber or pole for instance, an impression will be left thereon to indicate ownership, grade and kind of timber, as well as the inspectors number.

Another and very important object of the invention resides in a marking hammer con struction wherein the open face thereof is adapted to receive a plurality of adjustable letter or figure carrying discs so that the same may be disposed in such relation with respect to the face of the hammer permitting the raised letters or figures formed on the discs to leave an impression in an object struck by the head of the hammer.

Another and very important object of the invention is the provision of a marking hammer designed for a multiplicity of uses in various arts and one in which the parts are extremely simple in construction, easily assembled, rigid and durable, highly efficient in operation, practical and capable of being manufactured at a cost whereby its commercial possibilities are greatly enhanced.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming a part of the specification with the understanding however that the invention is not confined to any strict conformity with the showing in the drawings but may be changed and modified so long as such changes and modiiications mark no material departure from the salient features of the invention as specified in the subject matter being claimed.

In the accompanying drawings F gure 1 is a side View of the hammer.

Figure 2 is a face or bottom view. of the striking face. i

Figure 3 is an end View. I

Figure 4; is a sectional view taken on the line d-4. of Figure 1, and, I

Figure 5 is a further section taken on the line 5-5 of Figure 1.

Referring now to the drawings wherein like parts designate corresponding parts throughout the several views, the hammer comprises a poll, 5, a striking face ,6 having raised characters thereon indicating sown er'ship and the railroad inspectors number for instance. The poll is formed with a central eye 8 and peen 9 which may be graduated as shown at 9 to. measure the width and thickness of ties and timbers and is further provided with a curved pointed end 10. for the purpose of turning over ties and picking at knots or defects in the ties during examination thereof.

Extending through suitable apertures in the side walls 11, 12 of the hammer I have provided an axle or barrel 13 having grooves 14- near its outer ends to be engaged by screws or other fastening elements 15 where by the said barrel is held in position. Gradmg and grouping discs 16, 17 are rotatably mounted on the axle or barrel 13 said discs being provided with raised numbers and letters for instance 18, 19, thereon so that the same will be disposed below the flat face 6 of the hammer and leave an impression on an object when the same is struck. The front and rear sides of the hammer are open to expose the discs to view, it being observed that the combined widths of the discs 16, 17 is such as to lie within the opening and between the walls 11, 12 of the hammer.

The respective discs above referred to are provided with notches 20 on their outer edges to be engaged by the lug 21 of an L- shaped locking bolt 22 extending through horizontal apertures in the walls 11, 12 respectively. Horizontally disposed recesses 23 extending entirely through the poll 5 are each adapted to receive the arm of the locking bolt which is provided with a compression spring 25 and a head 26 threaded on the reduced end 27 of the arm 24 said head being adapted to lie within a recess 28 as clearly suggested by Figure 4 of the drawings.

Of course the locking bolts for the grade and group discs areindependently operable,

so that the head 28 of either may beforced inwardly to release the lug from the notch 20 so that the discs may be rotatedto the desired positions and dispose the marking characters or letters below the face 6-.

In assembling the device, the discs 16 and 17 are first inserted through the open front face of the hammer and the axle or shaft 13 passed through the apertures or recesses in thef side Walls of the said hammer Whereupontheiasteningscrews 15 may engage the grooves 14 and retain the barrel and discs thereon in position, Each locking bolt 22is then inserted through the horizontal recess in the poll Sand respective Walls of are hammer with the co ripression springs thereon andthe head 28 threaded on thelocking bolt so asjto permit the same to be actuated and" release the lug 21 -from the notches in the wheels,

Iii the accompanying drawings, I have "illustrated invention embodied in one form Way offeXample, and Which in practice hasbeenfoundto be highly satisfactory in obtaining the desired results. a It will be obvioushowever that other embodiments may Having shown and described my inveng tron, What I now claim as new and des re to secure byLrittersPatehtqf the U. S., 15-

A mark ng hammer ofthe class described comprising a hammer body open at its front and rear sides and provided with an opening therethrough communicating ",With the interior of the body, a stationary ax'le'and' inde pcndently rotatable marking discs carried thereby between the side Walls said discs having spaced notches or'rftheir outer" pe rip'heries and adapted to extenchbelow the striking face of said head and independ ently slidable locking elements engaging.

said notches in the 'vt her'eby the same may be kept in various arbitrary positions."
